.LOBSTER TRAP.

Application filed. June 28.'

The present invention pertains to a novel lobster trap, andthe object is the provi, En. ot a device ot this character which will be more durable inservice than the traps 'of present construction. f

This object is accomplished' by constructing the traine-work preferably aluniinium, v which has been found to withstand satisfactorily the action ot salt water. Nets through which the lobsters enter are'inserted in the ends ot the-traineworlr, and each net has an arched frame member which is detachably secured to the trame-work. Due' to these connections, the

" nets may readily be removed for repair or replacement. Y

il further feature' ot the invention resides in providing a door at the net which takes the lowermost positionwhen the trap Z0` is dra-wn out of the water. This door car# ries a float by which it is raised to open position when the trap is submerged under usual conditions. lhennthe trap is being drawn out of the water,l thelowermost net 251v is closed by this door 4so that the lobsters cannot escape through the lower end of the trap.

The invention is fully disclosed in the following description and in the' accompanying' drawings in which:Y

The trap is constructed upon a base which 'includes parallel slats 1 joined at the ends by bars 2. Arched members 3 are mounted upon the bars and are formed at their ends with flanges 4 which are secured to the ends of the bars preferably by means ot clamp screws 5. Another arched member 6 is placed transversely of the slats 1 intermediate their ends and secured thereto by rivets 7 or other suitable devices. Slots 8 are extended between the end arches 3 and secured thereto in any suitable manner, covering the same except :tor an opening 9 ot the 'trap of metal,`

which is Vretained at one side. The sla't 8 at the lower edge otl the opening has af pair.

ot strips 10 pivotalll'y connected thereto', and another series of slats 11 is secured ransversely oiA these strips in order to 'torni a door. The uppermost slat? of the door carries a screw clamp 12 as illustrated .in detail in Figures 6 and TQ The particular slat 8 which .lies adjacent the free cndot' themembeigll ot tliedoor carries a pivoted latch 13 which is receii'fable beneath the member r12 andA adapted'- to be secured thereby.

The various arches, slats and accessoriesI which have been described are constructed ot metal7 'preferably aluminium 4which has been found to be non-corrosive in sali water.

In each end ot the structure is inserted a net 'consisting yof a screen* 14 of conical formation. The inner end 15 oi each net open and held by anarched frame 16 which lits snugly within the corresponding arch o. The members 3 and 16 are held together byseveral screw clamps 17 so that the nets may readily be removedfor' replacement oi" repair. Y i v At one side of the device anvopening is formed through the slats Sas shown in' Fig'- ure 4, andthe ends of the 'broken slats are" joined by an arched frame' 18.A Within this verges toa. relatively ysmall openingf() at Y one end thereof asshown ifi-Fi'gmes 1 and 4.. The larger endA of this net carries a l ,trame-*21 which is secureditohthe surround-v 9:)

such as those previouslydescribed? To one endet the baseis pivoted a bracket- 23 to which may be attacheda towing rope for pulling the device out ot' the water. The

net at-the oppositeend has its smaller opening 15 provided with ahinged screen door 24 as shown in detail in Figure 2. This door carries an arm 25 to which is attached a float 26, where-by the door is normally held y in raised or open position when the trap is in the water. In the arch 6 is mounted a hook 27 or similar supporting member to which a bait may be attached.

When the trap is submerged, the door 24 is raised to open position as already stated,

and the remaining parts are permanently.

open. The lobsters which find their Way into the trap through the conical net-s do not escape, since it isl the tendency of the lobster to seek lower depths YVhen the trap is raised 'from the water while pulling on the bracket 23, the end nets 9 are placed in a vertical axis, and the lower one is closed by the door 24 so that the lobster' cannot escape through the adjacent opening. The trap is emptied by opening the door l0-ll and removing the contents in an obvious manner.

In the use of this device it has been t'ound that, due to the metallic character of the various parts, a. more durable and lasting construction may be obtained.L The nets which require attention are readily removed by loosening the screw clamps l?. The frame-work of the trap is less subject to breakage in handling than the ordinary Wooden traps, whereby the cost of maintenance is greatly reduced.

lVhile a specific embodiment of the invention has been illustrated and described, it is to be understood that various alterations in the details or' construction may be made without departing from the spirit ot the invention as indicated by the appended claims.

Having thus fully described the invention, what I claim as new and desire to protect by Letters Patent is:

l. A lobster trap Comprising a metallic frame-work, conical nets inserted therein, a door hinged to the opening of the net at the opposite end, and a float carried by said door.

work constructed of arched members and slats connecting said members, conical nets open at both ends, an arched frame at the larger end of each net,sa1d arched frames being secured in the arched members of said frame work, a door hinged in the open end ofone of said nets, and a float carried by said door.

5. A lobster trap comprising a framework constructed of arched members and slats connecting said members, conical nets open at both ends, an arched frame at the larger end of each net, said arched frames being secured in the arched members of said frame-work, a door hinged' in the open end of one of saidy nets, a float carried by said door, and a bracket pivoted to the end of the frame work opposite said door.

6. A lobster trap comprising a frame work constructed of arched members and slats connecting said members, conical nets inserted in the ends of said frame-work, a door hinged at the opening of one of said nets, a float carried by said door, and arde- Vice positioned Within said frame-work vfor supporting bait.

7. A lobster trap comprising a framework constructed of arched members and slats connecting said members, conical nets open at both ends, an arched frame at the larger end of each net, said arched frames being secured in the arched members of said frame-work, a door hinged in the open end of one of said nets, a float carried by said door, and a device positioned within said frame-work for supporting bait.

8. A lobster trap comprising a iframework constructed of arched members and slats connecting said members, conical nets open at both ends, an arched trame at the larger lend of each net, said arched frames being secured in the arched members of said frame-work, a door hinged in the open end of one of said nets, a float carried by said door, a bracket pivoted to the end of the :trame-work opposite said door, a'device positioned within said frame-work for supporting bait, and an emptying opening formed in said frame-work and a door hinged to the frame-work for closing said opening.

In witness whereoi` I have hereunto set my hand.
